12v 105ah car battery

Types of 12V 105Ah Car Battery

There are many types of car batteries, all of which have unique characteristics that make them different. Here are some of the most common types of 12v 105ah car battery that will be of interest:

• Lead-Acid Batteries

  Lead-acid batteries are the oldest and most commonly used batteries in vehicles. They are made of lead plates submerged in sulfuric acid electrolyte solutions. Lead-acid batteries come in two primary designs: flooded (wet cell) and sealed (AGM and gel). Flooded batteries have liquid electrolytes and require regular maintenance, while sealed batteries have fixed electrolyte levels and require little to no maintenance. Lead-acid batteries are cost-effective and have a high discharge rate, making them suitable for starting engines. However, they are heavy and have lower energy density compared to other battery technologies.

• Lithium-Ion Batteries

  Lithium-ion batteries are becoming increasingly popular in modern vehicles, especially electric and hybrid ones. These batteries offer high energy density, lightweight construction, and excellent charge/discharge efficiency. Lithium-ion batteries are less affected by temperature variations and have a longer lifespan compared to lead-acid batteries. However, they are relatively more expensive and require proper battery management systems (BMS) for safety and performance, which adds to the overall cost.

• Calcium Batteries

  Calcium batteries are a type of lead-acid battery with calcium alloyed to the lead plates. They offer several advantages over traditional lead-acid batteries, including improved corrosion resistance, reduced gassing during charging, and faster recharging capabilities. Calcium batteries are maintenance-free and provide reliable starting power. They are commonly used in modern vehicles for their longevity and performance benefits.

• AGM (Absorbent Glass Mat) Batteries

  AGM batteries are a specialized type of sealed lead-acid battery. They utilize fiberglass mats to absorb the electrolyte, immobilizing it within the plates. This design provides several advantages, such as spill-proof construction, better vibration resistance, and faster charge acceptance. AGM batteries are known for their deep cycling capabilities, making them suitable for applications requiring frequent discharges, like powering accessories in addition to starting the engine. They are more expensive than conventional lead-acid batteries but offer higher performance and durability.

• Gel Batteries

  Gel batteries are another type of sealed lead-acid battery. In gel batteries, the electrolyte is mixed with silica to form a gel-like substance. This gel formation enhances safety by reducing the risk of acid spillage and allows the battery to operate in various positions. Gel batteries have excellent deep cycling capabilities and a slow discharge rate, making them suitable for applications requiring prolonged energy withdrawal, such as renewable energy systems and mobility aids. However, gel batteries have relatively lower C-rate performance and charging efficiency compared to AGM batteries.

• Enhanced Flooded Batteries (EFB)

  Enhanced flooded batteries (EFBs) are an improvement over conventional flooded lead-acid batteries. They incorporate advanced materials and design elements to enhance cycle life, charge acceptance, and overall performance. EFBs are often used in vehicles with start-stop systems, where frequent engine restarts demand a reliable and durable battery. They offer a middle ground between standard lead-acid batteries and AGM batteries in performance and cost.

Specifications and Maintenance of 12V 105AH Car Battery

Below are the specifications of the 12V 105AH car battery;

• Battery capacity

  The total amount of charge the battery can store and give out is called its capacity. The 12-volt 105-amp hour battery can produce 105 amps for up to 1 hour or 21 amps for 5 hours.

• Voltage

  The 12-volt battery has 12 volts. This is the standard voltage for most car batteries. It consists of 6 cells that each produce 2.1 volts.

• Cold Cranking Amps (CCA)

  Cold Cranking Amperage (CCA) is the maximum current a battery can provide for 30 seconds at 0°F while maintaining at least 7.2 volts. CCA ratings are important for starting performance in cold weather. The CCA for a 12-volt 105-amp-hour battery is about 850-900 amps. This means the battery can deliver 900 amps of current for 30 seconds at 0°F and still power the system.

• Reserve Capacity (RC)

  Reserve capacity (RC) is the total time (in minutes) a fully charged battery can power a specified constant load (25 amps) until the battery is discharged. The reserve capacity for a 12-volt 105-amp-hour battery is about 150-200 minutes. This means the battery can supply 25 amps of current for 150-200 minutes before being fully discharged.

• Energy

  The energy of a 12-volt 105-Ah battery is equal to its voltage times its capacity. This gives about 1260 watt-hours (12 volts x 105 amp-hours = 1260 watt-hours). This means the battery can power a 12-volt 105-amp load for about 1260 watt-hours.

• Size and Weight

  Dimensions: Length 12.91 inches (328 mm), Width 6.77 inches (172 mm), Height 8.43 inches (214 mm), Weight: 77.16 lbs (35 kg).

Below are the maintenance of the 12V 105AH car battery;

• 1. Keep the Battery Clean

  Maintaining a clean battery is essential for its longevity and optimum performance. Dirt and moisture create a conductive path between the battery terminals, which can cause a slow discharge (drain) of energy from the battery. Use a brush to clean the terminals and a solution of baking soda and water. Once clean, ensure the terminals are dry.

• 2. Regularly Check the Voltage

  Users should regularly check the voltage of the 12V 105Ah battery to ensure it stays within the normal range. A healthy battery should have a voltage of 12.6V to 12.8V. A reading of 12.4V or lower means the battery is partially discharged, while 12V or lower indicates the battery is fully discharged. Discharging the battery to this level can damage it over time.

• 3. Keep the Battery Charged

  It is essential to keep the 12v105Ah battery charged for optimal performance and longevity. This can be done by plugging it into a charger after each use. Use a smart charger that stops charging when the battery is full to prevent overcharging. Proper maintenance of the charger is also essential. Clean the charger contacts regularly and keep the charger in a dry, clean place away from moisture and dirt.

• 4. Check the Connections

  Check all connections, including cables, clamps, and terminals, to ensure they are tight and not corroded. Loose or corroded connections can cause starting problems. If there are any corrosion issues, use a wire brush or terminal cleaner to remove it. Apply grease or anti-corrosion spray to the terminals to prevent future corrosion.

• 5. Ensure Proper Ventilation

  Proper ventilation is essential for lithium batteries during charging and use. For example, a well-ventilated area will allow the battery to charge faster and maintain its health. This is because a well-ventilated area can help regulate the battery's temperature. When there is no proper ventilation, the battery can heat up and, over time, this can damage the battery.

How to choose 12v 105ah car battery

Choosing the right 12v 105ah car battery is a task that requires thorough consideration of various factors that influence battery performance. Here are some of the key factors to keep in mind:

• Power Requirements

  Before making a decision, evaluate the power requirements of the vehicle. A vehicle with a lot of electronic gadgets and a bigger engine will need a battery with a greater reserve capacity and more cold-cranking amps.

• Climate

  Consider the climate of the area. A battery rated for higher CCA is needed for cold weather to ensure quick starts. On the other hand, in hot weather, a battery with greater reserve capacity is preferred since it can power the car while it overheats.

• Usage

  Determine how the vehicle is used. A vehicle used for short commutes needs a battery with a higher RC to run accessories, while a vehicle used for long trips can rely on a battery with a lower RC.

• Age and Maintenance

  An easily maintainable battery, like one with removable cell caps, is preferred. Consider the battery's age, as older batteries may not perform as well as newer ones.

• Cost

  Set a budget for the car battery, but don't skimp on quality. A high-quality battery may cost more initially, but it can last longer and save money over time.

• Brand Reputation

  Consider the battery's brand reputation. Select a well-known brand with a proven track record of quality and service.
